With the card set equip or not, my F1 items and %hp potion recover the same HP. Using Cursed Doll engraving.
Well i have the same set up and your 45% + 15% from the card is 60 - 25 from cursed doll.
So your potion will heal 35% if ur using the 45% one.
Re-equip it and now it worked, dont know what’s wrong
Ah it not works in chaos gates
